[Qemu-devel] [PATCH v4 0/4] Extend TPM support with a QEMU-external TPM

[Stefan Berger <stefanb@linux.vnet.ibm.com>]

The following series of patches extends TPM support with an
external TPM that offers a Linux CUSE (character device in userspace)
interface. This TPM lets each VM access its own private vTPM.
The CUSE TPM supports suspend/resume and migration. Much
out-of-band functionality necessary to control the CUSE TPM is
implemented using ioctls.

Stefan Berger (4):
  Provide support for the CUSE TPM
  Introduce condition to notify waiters of completed command
  Introduce condition in TPM backend for notification
  Add support for VM suspend/resume for TPM TIS
